I just read an essay called "Myths of Optimization in Golf", in which the authors attack the idea that working out will improve your golf game. They make a bunch of points having to do with the fact that a good drive isn't based on power, rather, technique, and adding power to your technique doesn't really improve your drive at all. But more importantly, they make the point that you only need strength for your tee shots and an average drive takes about 1.2 seconds to execute. Added up this equals abou 20 seconds worth of physical exertion per match. Even if you add in all your other shots, your looking at just over 1 mintue of physically playing golf. Throw in the fact that tour pros don't even carry their clubs, and you see that working out is for suckers!
